Quantum metric quadrupoles in elemental bismuth thin films
Rhonald Burgos Atencia, Pavlo Makushko, Gabriele Naselli +11
The authors demonstrate that third-order nonlinear electrical transport in centrosymmetric bismuth thin films originates from quantum metric quadrupoles, and they experimentally ob…

Soliton Pumping in the Rice-Mele Model with On-Cell Kerr Nonlinearity
Zhe Wang, Xi-Wang Luo, Bo-Ye Sun +1
We investigate the Rice-Mele model with on-cell Kerr-type nonlinearities, where the interaction depends on the total particle number within each unit cell rather than on individual…
